Definitions

  • This invention relates to alloy compositions and particularly to nickel-base cast alloys having high retention of ductility and high thermal stability on aging coupled with low thermal expansion and good oxidation resistance.
  • the present invention is directed to cast thermally stable high temperature nickel-base alloys and castings made therefrom and more particularly to an essentially non-ferrous, solid solution type, nickel-base alloy of the Ni-Cr-Mo class which possesses high thermal stability, high thermal strength, oxidation resistance up to about 1400°F., low thermal expansion and high retention of ductility on aging.
  • alloy having an Nv number between 2.23 and 2.31. All compositions herein are in weight percent unless otherwise stated.
  • composition which we prefer is:
  • said alloy having an Nv number as close to 2.28 as possible but within the range 2.23 and 2.31.
  • Pin molds were poured under vacuum using a 20-pound remelt charge from a master heat. The chemical analyses of the castings are reported in Table I. Each mold produced 10, 1/2-inch diameter pins approximately 4 inches long from which tensile test bars were machined for testing. Samples from each casting were submitted for (1) metallographic examination, (2) tensile testing at room temperature (RT) and 1400°F., and (3) stress rupture testing at 1400°F. under a load of 25,000 psi. In addition, two samples from each casting were tensile tested at room temperature after aging for 1000 hours at 1600°F. Appropriate specimens were also machined from the bottom casting date and submitted for oxidation testing as follows:
  • Static Oxidation Exposed to dry flowing air (7 cfh) at 1600°F. for 500 hours.
  • Dynamic Oxidation Exposed to high velocity combustion gases (No. 2 fuel oil) at 1600°F. for 300 hours. Specimens were cycled out of the hot zone every 30 minutes.
  • Table II summarizes the mechanical properties of the alloy of Example I.
  • Table III summarizes the environmental resistance of the castings.
  • the alloy of this invention was compared for elongation against two well-known commercially available, high performance nickel base cast alloys, Hastelloy* alloy B and Hastelloy* alloy C.
  • the compositions of the alloys are set out in Table IV.
  • Cast pins of the alloy invention specified in Example II were made by vacuum melting and pouring techniques. These pins were subjected to isothermal aging for various lengths of time and then machined into tensile test bars.
